Linear Motorized Table Jean-Carlo McLure, James Hunton
Design Problem Vermont Technical College does not have a linear motorized table for use in controls labs. Due to the college not having this piece of equipment, some of the labs done for the controls class are either very hard to prepare and execute or the labs just can not be done.
Design Solution The solution to this problem is for our group to make our own linear motorized table using specifications given to us by the instructor, John Murphy. Using these specifications, we will characterize create a controller to work with the board.
Design Function The function of this linear motorized table is to be a versatile lab platform. For this project, we are using the table to create a scaled down model of a crane that we can analyze, characterize and control.

The Control System Standard control system Given H(s) equal to one. Control system as it relates to our project. Gp(s) = Plant/ system Gc(s) = Controller Gc(s) + Gp(s) = G(s) R(s) = Stop signal Y(s) = Table and pendulum response Feedback will be given from the table position sensor.
